Title: Handover method for base station device
Inventor: KOJIMA MASAHIKO
IPC: H04W48/04
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to stop communication with a base station device regulated at its handover without having effect on a mobile communication system and to keep the device in a surely maintainable state by specifying a movement destination base station device due to handover on the basis of a radio state periodical report from a mobile terminal station. SOLUTION: The mobile communication system 10 has a mobile terminal station 11, base station devices 12a to 12c and a base station control device 13, where the base station 12a is a base station to be maintained. The terminal station 11 sends a periodical report to the control device 13 on the basis of receiving levels from individual devices 12a to 12c. On the basis of the periodical report information the control device 13 requests the terminal station 11 to select the device 12b as a handover destination. The terminal station 11 excludes the device 12a from communication targets and adds the device 12b to the communication targets.

IPC: G01N21/35
Filed: 1987-02-13
Abstract: PURPOSE:To miniaturize and simplify a device by forming chromatograph directly on an ATR crystal and making spectroscopic measurement. CONSTITUTION:After a sample liquid is supplied to a fixed phase 2, the ATR crystal 1 is loaded together with a vessel 3 into a sample chamber of a Fourier transform IR spectrometer. The incident direction of IR light I on the crystal 1 intersects with the development direction of the sample. The respective separated sample components move toward the upper part of the crystal 1 according to a development speed. The first separated sample component A arrives at the total reflection region of the IR light I in the crystal 1. The IR light is thereby intruded into the component A held in the fixed phase 2 and is subjected to the influence specific to the component A near the total reflection surface of the crystal 1. The influenced IR light is taken out of the crystal 1, by which the total reflection absorption spectra are obtd. The device is thereby miniaturized and simplified.

Title: Flow rate control valve
Inventor: TANAKA MAKOTO
IPC: F16K31/02
Filed: 1993-01-26
Abstract: PURPOSE:To reduce the number of parts and to make accurate flow rate control possible through a small type valve, by, in a flow rate control valve to control an opening and closing quantity between a valve body and a valve seat through the displacement of a laminated piezoelectric element, giving only the load of the valve body to the laminated piezoelectric element in a state where voltage is not applied to the laminated piezoelectric element. CONSTITUTION:In a flow rate control valve in which the valve body 23 of a diaphragm elastic body is moved by the displacement of a laminated piezoelectric element 19 to control an opening and closing quantity between the valve body 23 and a valve seat, only the elastic load of the valve body 23 is given to the element 19 in a state where voltage is not applied. Thus, the load of the valve body 23 of the diaphragm elastic body acts directly on the element 19 to make the valve body 23 directly pressingly hold the element 19. Namely, since the element 19 is not affected by a coil spring being used hitherto, the valve body 23 can obtain displacement responding to applied voltage to surely control the opening and closing quantity between the valve body and the valve seat for making constantly accurate flow rate control possible.
